ALFRED E. STACEY, JR., 0] ESSEX FELLS, NEW JERSEY, ASSIGNOR' TO CARRIER EN- GINEERIN G CORPORATION, OF NEWARK, NEW JERSEY OUTLET AND REGULfL'IOfi FOR AIR AND THE DUCTS Application filed July as, 1921. Serial no. 488,286.

This invention relates to outlets'ordischarge regulating means for air ducts such as are employed in ventilating, air conditioning and other. systems for delivering air at required places the rooms of buildings.

It is usual in such systems having air supply ducts, to extend the ducts along the building or room to which the air is to be supplied and to provide the same with one or more outlets located along the side or sides of the duct as may be necessary to discharge the -ain at the required points.- Means of some sort are commonly provided at the outlets for regulating the discharge of the air. In some instances. pivoted dampers or shutters are used. Deflectors arranged in the duct, adjacent to the forward ends of the discharge openings, where one duct is provided with a plurality of the outlets at diflerent points in its length, have also been employed to insure the proper discharge of the air from the several outlets. Such deflectors are objectionable as they obstruct more or less the flow of air in the duct and also tend to cause the discharge of a greater volume of air from the ends of the outletsat which the deflectors are located, thus causing an unequal discharge of the air from different parts of the outlets. The pivoted dampers or shutters enable the volume of the discharge from the outlet to be regulated by opening 'or closing the dampers or shutters more or less, but in equipped with regulators or deflectors so,

' edge 13 which is adapted to extend mto the ing an equal distribution of the discharging thus adjusting the dampers or shutters, their angularity with reference to the outlet is changed, so that the air is delivered'indifferent directions in the diflerentadjustments, and the discharge of the air cannot be regulated, and'at the sametime, the air caused to be delivered always in the same direction, which is usually important.

One object of this invention-is to provide an outlet for air ducts and the like, which is constructed and arranged that the volume lated as required, while nevertheless insurair throughout the area of the outlet and preventing a change in the direction of discharge of the air. g

Other objects of the invention are to provide an outlet equipped with deflectors or regulators, which is made as a complete'unit and can be readily applied to the duct vided with a simply by attaching the casin' g of the outlet, to the wall of'the duct at the required point; and also to improve the construction of the outlets and discharge regulators for air ducts in the other respects hereinafter described and set forth in the claims.

In the accompanying drawings:

Fig. 1 is a plan view of an air duct pro- 4 plurality of outlets embodying the inventio Fig. 2 is an enlarged sectional plan view of one of the outlets. r

Fig. 8 is a front elevation thereof.

Figs. 4 and 5. are sectional elevations thereof; on line 44, Fig. 2, Fig. 5 being on a larger, scale.

Fig. 6 is a detail section of one of the hinge joints for the regulator plates.

Fig. 7 is a fragmentary sectional plan view of the outlet showing by full and broken lines, the closed and partly opened positions of the regulator plates.

A represents an air duct which may be of any usual or suitable construction and B represents the outlets, of which any desired gumber one or more, may be used on the not.

Each outlet comprises an open ended frame or casing 10 preferably made of sheet metal and of rectangular shape, car re ators and deflectors and adapt e d t o hi securedto the wall of the duct-so as to project' outwardly therefrom around an outlet opening 0 in the wall of the duct. shown, the casing of the outlet is stiffened or strengthened at its outer endby folding over the edge of the sheet metal from which the casing is made and bending the doubled portion to form an outwardly projecting marginal flange 11; and the inner end of the casing is bent to form a double thick-- ness shoulder 12 which is adapted to bear, against the outer face of the wall of the duct, and an inwardly projecting flange or duct through the outlet openingC in the As shown in the drawings,

discharge in the same direction from the outlet regardless of the angular adjustment of the regulating plates. The adjustable plates.

are pivoted at their outer ends in the casing at or adjacent to the inner ends of the stationary deflector plates, and their inner ends are adapted to swing for varying the opening of the outlet and thus regulating the discharge of-the air through the same. Preferably, one of the adjustable plates is hinged to the inner end of, each 'of the stationary deflector plates so as to form an adjustable continuation of the latter, and the inner ends of the adjustable plates are pivotedor otherwisesuitably attached to a connecting bar 16 whereby the several regulator plates are caused to swing in unison. the outer ends of the stationary deflector plates are se-. cured in the casing 10 by nails 17 driven through holes in the top and bottom walls of the casing into tubular beads formed on the ends of the plates, and the inner ends of the plates are secured in the casing, and the adjustable plates hinged thereto in-a similar manner, by nails 18 driven through holes in the top and bottom walls of the casing and through alined tubular beads formed on the adjacent ends of the stationary and adjustable plates. This manner of securing the plates produces a desirable and inexpensive construction, but the deflector plates and regulator plates could be mounted in the casing in any other suitable way. The pivoted plates can be secured to the connecting bar 16 in any suitableway, as for instance, by nails passing through holes inthe bar into tubular beads formed on .the inner ends of the plates. The bar is thin and lies between one wall of the casing and the adjacent ends of the plates and is adapted to slide on said wall. 7

Any suitable means may be provided for securing the pivoted regulator plates in adjusted positions. -For instance, as shown, a bar 19 rovided with a. series of holes 20 is attached to one. end of the connecting bar 16, and a securing bolt or fastening device 21 of any suitable sort connected to the casipIgIO'can be secured in one or-another of t e ulator plates, in the desired osition.

The swinging regulator p ates 14: being ivoted to the inner ends of the stationary eflector plates 15 form in efl'ect, adjustable continuations or sectionsof the latter so that while the volume of the discharge can be regulated as required by appropriate 'ad-' justments of the pivoted inner sections of the deflectors, the stationary outer sections of the deflectors always direct the discharge of the air in the same direction from the outlets, that is preferably substantially erpendicularly from the duct A. Since t ere are a plurality of the. deflectors disposed holes 20 in the bar 19 to'secure the regg- I 3. An outlet for ducts for air and the like,

substantially equidistant across the width of the outlet, they cause a substantially uniform discharge of the air from all portions of the outlet. Preferably the swinging sections of the deflectors terminate at their inner ends about at the plane of the outlet opening C in the wall they tend to deflect the air outwardly through the outlet, but they do not project far enough into the duct to objectionably obstruct the flow of air therethrough, and preferably, the stationary sections of the deflectors extend perpendicularly to the length of the duct A, except the two end plates, which diverge outwardly somewhat.

I claim as my invention:

1. The combination with a duct for air and the like having a lateral outlet opening in a longitudinal wall thereof, of regulator plates which are arranged adjacent said opening for controlling the discharge therefrom and are adjustable from a closed position outside of said duct to an inclined open position in which their inner edges are opposed to the direction of flow of the fluid through the duct and terminate substantially in alinement with the wall of the duct, and relatively stationary deflectors which extend outwardly beyond said regulator plates at angles to said wall.

2. An outlet fo'r ducts for air and the like,
